Final answer:
The selling price per unit if Garcia uses a markup of 10% of total cost is approximately $349.58.
Step-by-step explanation:
To find the selling price per unit, we need to calculate the total cost per unit and then add a markup of 10% to it.
Total cost per unit = direct materials + direct labor + variable overhead + variable selling, general, and administrative costs + fixed overhead costs / number of units produced
Total cost per unit = $121 + $51 + $66 + $24 + $677,000 / 12,100
Total cost per unit = $121 + $51 + $66 + $24 + $55.95
≈ $317.95
Markup = 10% of total cost per unit = 0.10 * $317.95
≈ $31.79
Selling price per unit = total cost per unit + markup
= $317.79 + $31.79
≈ $349.58
